TRUCK.

SPECIFICATION forming part of Letters Patent No. 623,463, dated April 18, 1899.`

To au whom t may concern:

Beit known that I, ARTHUR L. CHURCH, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Trucks, of whichl the follow ing is a specifica-tion.

The object of myinvention is to make a cartruck that will be perfectly rigid and comparatively light and cheap. I utilize in the main parts of the truck shapes that can be procured in the open market.

My invention is especially applicable tothe trucks of electric locomotives where a certain amount of room is required for the motors; but it will be understood that the invention can be used in connection with any rollingstock.

In the accompanying drawings, Figure l'is a plan view of myimproved truck-frame. Fig. 2 is a side view. Fig. 3 is a section on the line 3 3, Fig. l. Fig. 4 is a detached perspective view of the main frames composingthe truck. Fig. 5 is a detached perspective view of one of the stittening-plates. Fig. 6 is a sectional view on the line 6 6, Fig. l; and Figs. 7 and 8 are views of modifications.

The side frames A and transom or crossframe B are made up of wide channel-beams having shallow flanges, as clearly shown in Fig. 4.

The channel-beams D form the outside plates of the two side frames, and the channel-beams D, which are bent as shown in Fig. et, form the transom and the inside plates of the side frames.

The beams D and D are bolted or riveted together, as shown in Fig. l, suitable spacing plates or sleeves being inserted between the,

parts at proper intervals. These channelbeams can be procured in the open market, and the beams D can be bent by an ordinary hydraulic press. The ends of each plate are cut away so as to form the openings CZ for the boxes of the axles, and to the ends d are attached the movable pedestals E, the pedestal E' being rigidly secured to the plates. The pedestalE has a pivot-pin e,on which it swings and is held in place not only by the link E2, but also by a bolt e', passing through the plates D D and through an opening in the A flange e2 on the pedestal rests against the under side of the plates, so that Application led .Tune l, 1896. Serial No. 593,841.- (No model.)

when the pedestal is in position it is perfectly rigid; but when the link is detached and the bolt drawn it can swing on its pivot, so as to allow for the ready removal of the box.

In order to add strength and stiffness to the structure, I mount at the junction of the side frames and transoms, above and below the channel-beam, plates D2, one on the'upper side and one on the under side. These plates are simply sheared from ordinary sheet metal, requiring no special tools, and are riveted or bolted to the tianges of the channel-beams. The top plates D2 have at one side openings cl2 for the reception of one of the levers of the braking mechanism, as shown in Fig. 7.

Plates D3 extend from one transom to the other oneach side of'the center plate e at .the

top to stiften the structure. The under side is preferably left clear for the ready removal of the springs when necessary.

The bolster F is made of a flanged channelbeam and is preferably braced at the center directly under the center bearing-'plate f and has suitable side bearing-blocks f.

The swinging frame G carries springs g g and is hung from studs cl3, secured to the transoms I3- by links G. These links are in the present instance within the transoms, so that they are protected. The studs d5 are attached through openings in the beam, the upper end of each link G resting between the beams and the flange of the bolster F. The springs I for the boxes are mounted between the plates D D in the side frames and are also protected.

In some instances I may extend a bottom plate under the swinging plate G from one side frame to the other, so as to inclose the space between the transoms in which the bolster and swinging frame are mounted, as shown by dotted lines in Fig. l.

It will be seen by the above description that a truck can be made from ordinary metal shapes now on the market in a very cheap and substantial manner and whichpwill be fully capable of withstanding the strains to which an electric-locomotive truck is subjected. At the same time it can be made comparatively light and with very few of the parts exposed, leavin g ample room for the motors and their parts.

, to the outside of each beam D and passthem from single lengths, which are readily obtainable on the market.

In Fig. 7 I have shown the swinging frame G below the transom and connected to links hung on the outside. This form is preferred when narrow channel-beams are used for the frame of the truck.

l. The combination in a truck structure of channel-beams bent to form the transom and portions of the side frames, with channelbeams forming the side plates of the side frames, the beams being secured together with their flanges abutting and extending over the boxes and forming cavities for the boX- springs, substantially as described.

2. The combination in a truck structure, of bent channel-beams and straight beams with plates I)2 secured to thestructure at the junotion of the bent channel-beams and straight beams and having openings for the reception of the dead-levers of the brake mechanism, substantially as described.

3. The combination in a ear-truck, of the transoms composed of deep channel-beams, a bolster formed tothe shape of a channelbeam, a swinging frame G supporting the bol- Y ster, pins on the inner side of the transoms,

links hung to the pins and'mounted between the transom and bolster and carrying the swinging frame, the said bolster, swinging frame and links being within the space inclosed by the transoms, substantially as described. y

4. The combination in a car-truck, of the transom made of two channel-beams, the bolster and swingingframe, its links and springs interposed between the bolster and swinging frame, the several parts being within the transom, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.` ARTHUR L. CHURCH.
